    Is This Camshaft Reusable? Or Too Pitted?

    For that one bolt, I believe I pulled the bracket off that covers the bolt. The picture points out your issue glad you got it whipped. To tighten to 240 lbs. I have an Ingersol Rand 1/2" air impact. I tighten with it and leave it. Have not held the crank to do this yet. Is it perfect...

    500+ rwhp out of a 5.3?

    As others mention, yes you can get there but not naturally aspirated. You need a blower, turbo or nitros. Once done you need to know your engine is now a time bomb. Which part will fail first? My son has a twin turbo on his LS, it is an early 5.7L LS block, and is making right at 1,000...

    Tech 2 scanner vs Autel

    With Launch all updates are free for 2 years, once that time is up it is $400 per year to keep it operating. Before retiring I worked on all makes so it was very handy. I could jump from a Mercedes to a Suburban and it took care of both.

    2005 Chevrolet Tahoe Z71, 5.3 non flex fuel. Hard starting.

    Nice work, you tracked it down and fixed it. That always feels good.

    Tech 2 scanner vs Autel

    I have a Launch X431V +, it is a very good tool, bi directional, does most programming needed, ABS, brake Bleeding, TPS sensor coding, module programing. Key programming. The thing to look at when buying, does the scan tool have an annual fee to keep it working and updated. I hate that the...

    Oil pan secondary valve

    With the AFM deleted I agree with plugging the pressure relief inside the oil pan. It is not needed with AFM removed and a plug will never stick open and cause low oil pressure. I am curious what you did in the AFM manifold to seal up those oil passages. Did you install the Non AFM manifold...

    Is This Camshaft Reusable? Or Too Pitted?

    When you torque the other bolts take a small open end wrench or whatever tool you can get in there with. Test the tool you need to use on the already torqued bolts. Once you know how tight they feel with the wrench you need to use just do the torque on the hard bolt by hand and trust your feel...

    Noise from engine 1997 Tahoe 5.7

    That would save a ton of work.

    Noise from engine 1997 Tahoe 5.7

    I had a flex plate crack, had the odd noise at the rear of the engine. Tranny has to be slid back to change it, nothing fun about that job if that is it.

    Is This Camshaft Reusable? Or Too Pitted?

    I have never seen a pick up tube with more than 1 Oring. Maybe a previous owner doubled them up? GM does not make lifters, have not made them in 30 years. Eaton does make Lifters, Top Line USA does make lifters at the HyLift plant, I have used both Eaton and Topline Hylift and they work as...

    Is This Camshaft Reusable? Or Too Pitted?

    The cam looks fine to me, if you don't think it is good have a shop polish it, it will look brand new again. Roller cams last one heck of a long time. The same design goes into the Duramax Diesel, no one tears them down for a cam and they last 300,000+ miles. Not saying it is pretty but I...

    Is This Camshaft Reusable? Or Too Pitted?

    Unless there is hidden damage not shown in the photo that is what used roller cams look like. With roller lifters they do not wear down. Failed roller cams are caused by a bad lifter. Owners run the broken AFM lifters while they are clacking till the cam gets damaged. Does not look like...

    Is This Camshaft Reusable? Or Too Pitted?

    I always remove the oil pan and replace the Oring on the pick up tube. Since you have the timing cover and cam out you can remove the oil pump and shim the pump spring for a little extra oil pressure. With the new cam install and no more AFM lifters the second pressure relief valve in the pan...

    Is This Camshaft Reusable? Or Too Pitted?

    Geotrash Dave nailed it and I forgot to point this out. When you pull the heads coolant will seep into the head bolt holes in the block. These must be blown out before the heads are installed or you will be torquing against the coolant in the threaded holes and not torquing the head. Double...

    Is This Camshaft Reusable? Or Too Pitted?

    If this is all new to you there are a few things to be aware of. Torquing the NEW head bolts has several steps. I found the easiest and least chance of messing this up is to torque all bolts to the first step specs. Then take a paint pen, I use white so it is easy to spot as I work. Mark...

    Is This Camshaft Reusable? Or Too Pitted?

    The tensioner is a wear part so I was assuming you would replace it?

    Is This Camshaft Reusable? Or Too Pitted?

    First align your timing sprockets so they are in the perfect position, marks aligned properly. This sets you up for the future install, crank and cam in proper position. I have done several, I don't remember fighting any of them. Remove the bolts holding the cam sprocket to the cam and...

    Engine Pinging

    Pinging in the engine is either a lean fuel supply, low octane fuel or over advanced timing. A lean burn condition / detonation can melt a hole in a piston. Make sure you find the cause of your pinging or a piston may melt in the new engine also. In most new engines you bolt up the old...

    Engine Pinging

    Running on old gas is a very bad idea. it does not burn clean, it will shellac your pistons, lays a clear lacquer like coating on the piston heads, although pretty to look at it is sticky to touch. Not good for the engine. It can also coat the valves and make them stick in the head. If this...

    Is This Camshaft Reusable? Or Too Pitted?

    This is a roller camshaft, not a flat tappet camshaft, if I could feel anything with my fingernail I might give it a slight buff with emory cloth to make sure there are no protrusions. Clean it, oil it and install my new lifters. Yes I have done probably a dozen GM repairs in the last couple...

    Oil Pressure Woes - Need Advice/Help

    I have disabled a couple of AFM units years back, there is a kit available to mechanically disable them out of a place in Texas, works fine. I found Suburbans could still give 18 mpg or more on flat ground with AFM disabled. Once the laws about smog checks tightened up I have gone to a factory...

    Oil Pressure Woes - Need Advice/Help

    My question would be, have you verified your dash oil pressure gauge is working properly?

    2015 Yukon Denali - Engine Failure - Sell or Fix?

    Contact the Production Engine Rebuilders Association, PERA, they can tell you where members reside in every state. The PERA members are typically shops that build over 100 engines per month. Jasper Engine is a big rebuilder but there are many more coast to coast still building engines.

    6L80 to 10L90 swap? Seeking insight on a 10 speed transmission upgrade

    If I was going to spend $7500 on a 10 speed swap I would find a much younger truck to put it in. I think you said your rig has 253,000 miles already? I would start with one young enough so I could enjoy the entire truck for many years with that new 10 speed installed. I installed a fully...
